KONI don't make bike shocks anymore, but.........
They sold all the old stock, drawings and rights to an Austrailian company called IKON (anagram of... KONI).
You can still buy the shocks off your bike and they are fully rebuildable (they do supply the individual parts to rebuild the old shocks).
If it ain't broke, don't fix it.
